Single dimension tracking based snow-proof solar photovoltaic power generation device

Abstract

The invention discloses a single dimension tracking based snow-proof solar photovoltaic power generation device. The device includes a solar photovoltaic assembly, a fixed support, a stroke adjustingdevice, a power output line, a combiner box and an inversion device. One side edge of the solar photovoltaic assembly is hinged to the fixed support while the other side edge is connected with the stroke adjusting device. The stroke adjusting device includes a thread sleeve, a thread rod and a transmission device. The top end of the thread sleeve is hinged to the solar photovoltaic assembly. The bottom end of the thread sleeve is threaded with the top end of the thread rod. The bottom end of the thread rod is mounted on a rotary shaft. A plate-shaped base is hinged to the fixed support. By adopting the above scheme, the stroke adjusting device adjusts the included angle between the solar photovoltaic assembly and the horizontal plane, so that the solar photovoltaic power generation efficiency is improved. When snowing, a board of the photovoltaic assembly can be adjusted to be perpendicular to the horizontal plane, so that snow accumulation on the board of the photovoltaic assembly isavoided.

Description

technical field [0001] The invention relates to the field of solar photovoltaic technology, in particular to solar photovoltaic equipment. Background technique [0002] At present, solar photovoltaic power generation devices are mostly fixed installation power generation systems, that is, solar photovoltaic modules have a certain angle with the ground and are fixed on the bracket. This installation method is simple and convenient, but due to the angle between the photovoltaic panel surface and the ground This will reduce the utilization rate of sunlight and reduce the power generation efficiency. At the same time, in snowy weather, the snow will accumulate on the board surface, and the photovoltaic modules will not be able to generate electricity normally. It is very troublesome to clean the snow, which will affect the entire photovoltaic system. power station applications.

[0002] At present, solar photovoltaic power generation devices are mostly fixed installation power generation systems, that is, solar photovoltaic modules have a certain angle with the ground and are fixed on the bracket. This installation method is simple and convenient, but due to the angle between the photovoltaic panel surface and the ground This will reduce the utilization rate of sunlight and reduce the power generation efficiency. At the same time, in snowy weather, the snow will accumulate on the board surface, and the photovoltaic modules will not be able to generate electricity normally. It is very troublesome to clean the snow, which will affect the entire photovoltaic system. Power Station Application

There is also a solar photovoltaic tracking system in the prior art, which can automatically adjust the direction of the solar photovoltaic module panel surface according to the different incident angles of solar light, and is always perpendicular to the incident light of sunlight. This technology can maintain the efficient use of solar light, but all Azimuth tracking, complex control system, high manufacturing cost, difficult to maintain, not conducive to popularization and use; at the same time, in snowy weather, photovoltaic module panels are prone to snow accumulation, and cleaning is more troublesome, which affects the efficiency and effect of solar photovoltaic systems

It has affected the application and promotion of solar photovoltaic power generation, and the above problems need to be solved urgently
